Yes, rainwater collection systems need consistent attention. Falling behind on general maintenance of filters, UV lights, gutters, leaf baskets, etc. can lead to contaminated water. We encourage a thorough review of your system at least every 3-6 months (depending on size of the system). Many people opt to replace their own filters, etc. but we also offer all of our customers the option to employ our skilled technician team to provide this as an ongoing service.
